To all whom it may concern.-

Beit known that I, EDWARD P. FITZGERALD, a citizen of the United States,residing at Lena, in the county of Stephenson vand State ot Illinois,have invented a new and usefullmprovement in a Combined Pipe-Holder andVise, of which the following is a specification.

My invention relates to improvements in apparatus employed in raisingand lowering the pump pipes in Artesian and other wells, and also forretaining or holding such pipes in .position whenever it is desired toremove one or more joints of pipe, and also for securely clamping andholding the pipe when a portion of the same is to be cut off or screwthreads to be cut on the end thereof without removing the pipe from thewell. Y

The object ot` the invention is to provide an improved apparatus for theabove purpose which shall possess superior advantages with respect toefficiency in operation.

The invention consists in the novel construction and combination ofparts h'ereinafter fully described and claimed. i

In the accompanying drawings, Figure l is a plan view of an apparatusconstructed in accordance with my invention. Fig. 2 is a detailperspective View of the cap. Fig. 3 is a similar view of the movableclamping-jaw. Fig. 4 is a similar view of the movable crosshead and theright and left handed screw. Fig. 5 is a similar View of theclamping-plate and its pivoted rod. Fig. 6 is a similar view of thetongue and its hinged plate. Fig. 7 is a similar view of the linkconnected with the bracket, provided with bolt holes 4, for the passageof bolts by which it is secured to the base and the plate securedthereto. This cap or bracket when in place forms a housing for a movableclamping jaw 5, recessed at opposite sides, at 6, and forming shoulders7. The numeral 8, designates bolts passing through the cap or bracket,and forming guides for the jaw. The shoulders 7, form stops againstwhich the bolts S, abut to limit the movement ot' the jaw. At its innerend the said jaw is formed with a V shaped recess provided with angularteeth 9, and at its outer end is formed with a central leit hand screwthreaded opening l0, to receive the correspondingly threaded inner endof a vise screw 12. These left handed threads only extend part way thelength of the screw, the balance of which is formed with right handthreads. At its outer end this screw is provided with a head 13, throughwhich passes an,-.65AA

operating bar 14. The numeral 15 designates a movable cross head,provided with a central right handed screw threaded opening, through fwhich the said screw passes and by means of which it is operated. At oneend this cross head is provided with a rod 16, which is screw threadedand which passes through a corre-- spondingly threaded opening in thecross head. It is provided with a nut 17, by which it may be adjusted.The opposite end ot' this rod is bifurcated and pivoted to a clampingplate 18, having a semi-circular recess in its inner edge provided withangular teeth 19. At the other end this plate is provided with notches20, ,with which engagesan oblong loop 21, of a link 22, which isconnected by means of an eye joint with an adj ustablc screw rod 23,passing through one end of the cross head, and provided with anadjusting nut 25.

Secured to the plate 2, is a short metal plate 26, provided with slots27, through which pass bolts 28, provided with nuts 29. By this meansthe said plate may be adjusted so as to bring it nearer toror fartherfrom the openings in the base 1 and plate 2, according to the size ofthe pump pipe. At its inner end plate 26 is formed with apertured lugs30, which embrace a similar lug 3l, on one end ot' a tongue 32, whichlugs in connection with a pin 33, form a hinge joint. This tongue tapersoutwardly from its joint to the opposite end which is flattened andformed with a semi-circular recess'with a sharp edge vto bite IOO back.The pump pipe is then passed th rough the openings irl the'loase andplate .2, and the tongue then thrown forward so as to contact with thepipe. The pipe may now be raised by any suitable means, the tongueoffering no resistance thereto. XVhen the pipe is released, however, itwill be prevented from downward movement by the tongue biting into thesame, and pressing it against the clamping jaw.

When used to clamp and hold the pipe the apparatus is brought intoposition asabove described. The link is then engaged with the clampingplate, and the vise screw rotated,`

the left handed screw threaded end of which acting in thecorrespondingly threaded opening in the clamping jaw will force thesaine inwardly. At the saine time the right handed threads 'of the screwwill move the cross head outwardly or in the opposite direction andthrough the medium ofthe'connecting rod and link will draw the clampingplate inwardly so that the pipe will be securely clamped between saidplate and jaw and securely heldin place.

Having thus fully described my invention, what I claim is- 1. In anapparatus of the character described, the combination with a base havingformed therein an opening or passage for a pipe, of two clamping jaws,5, 18, arranged on opposite sides of said opening in the base, thejawhaving an internally threaded socket formed therein and openingthrough its outer face, a cross head arranged beyond the outer face ofthe jaw 5 and connected with the jaw 18, said cross head having aninternally threaded passage, the threads of which eX- tend inv theopposite direction to those in the socket in the jaw 5, and an operatingscrew provided for a portion of its lengthwith a thread, adapted toengage the thread in the passage in the cross head, and at one end withv'an oppositely extending thread which engages with the thread in thesocketed jaw whereby both jaws will be simultaneously moved by the screwin opposite directions, substantially as set forth.

2. In an apparatus of the character described, the combination with abase provided with an aperture or passage, of two jaws, 5, 18, arrangedon opposite sides of said opening in the base, the jaw 5 having aninternally threaded socket which opens through the outer face thereof, across head provided with an internally threaded passage in line with theaforesaid socket in the jaw 5, adjustable connections between the crosshead and the jaw 18, and an operating screw provided with oppositelythreaded sections adapted to respectively engage with the thread in thecross head and in the socket of the jaw 5, whereby said screw is adaptedto simultaneously move both jaws in opposite directions, substantiallyas set forth.

3. In an apparatus of the character described, the combination with abase provided with an aperture or passage, of two jaws, 5, 18, arrangedon opposite sides of said opening in the base, the jaw 5 having aninternally threaded socket which opens through the outer face thereof, across head provided with an internally threaded passage in` line withthe socket in said jaw,'a rod pivotally connecting the cross head andthe jaw 18 on one side of the opening in the base, a link connected tothe cross head on the opposite side of the opening in the base andadapted to be detachably connected to the jaw 18, and an operating screwprovided with oppositely extending threads adapted to respectivelyengage with the threaded passage in the cross head and the socket in thejaw 5, substantially as and for the purpose specified.

4.. In an apparatus of the character described, the combination with thebase and plate having openings therein,the bracket or cap forming ahousing, the clamping jaw, having teeth at its inner end and cut away atopposite sides forming guideways and shoulders, and the guide pins, ofthe right and left handed screw the inner end of which engages withascrew threaded opening in said jaw, the cross head having a screwthreaded opening through which said screw passes, the adjustableconnecting rod secured to said cross head, the clamping plate, providedwith teeth,
